LIGHT SOURCES NOT OTHERWISE PROVIDED FOR
Definition statement
This subclass/group covers:

The following light sources per se:

  • Luminescence light sources that do not use electricity in the generation of their light (e.g. chemoluninescence, triboluminescence or thermoluminescence),
  • Light sources that are created by charges of explosive or combustible materials (e.g. illuminating flash devices)
  • Light sources that are not provided for in another subclass.
